'75 cb750.
I'm working on a carb rebuild. I've read that the factory puts the clip on the needle on the middle groove. But, when I got mime apart, a PO had them set on the very last groove (bottom most groove I'd you're holding them with the point down).
So, my question: what groove would be best for my setup? I know it can vary, bit I need a good starting point.
